[QUOTE="JWD, post: 8662239, member: 676052"] I ordered the head unit, wiring harness from crutchfield as well as a little controller module thing and another harness so the steering wheel controls will work. However, looking at the instructions provided by crutchfield, it says that both of the wiring harnesses need to connect to the factory 20-pin connector. I'm pretty sure you can't stack them/connect more than one in this way. The whole reason i ordered through crutchfield was so i wouldnt have to splice into my factory wiring, which makes me uncomfortable (i dont want to create a problem). I thought maybe i could splice the two harnesses together, but they dont have leads in the correct pin positions. Is there a way to splice a wire into one of these multi-connectors without cutting into my factory wiring? Basically i have this: [steering wheel] --> [factory 20pin connector] <-- [crutchfield steering adapter harness] <--[control module] --> [head unit] but at the same time i have [factory 20pin connector] <--[crutch. receiver harness] <--[head unit] Either of these are easy enough by themselves, but i'm trying to do both at once, and as far as i can tell i can't snap both harnesses onto the factory connector at the same time.
